1a) If the rate of change, W, is inversely proportional to W(x) where W is always greater than 0. If W(1)=25 and W(4)=17, then find W(0)
1b)assume an object's weight, W, is proportional to its height, H. Does it make sense to use differential equations to model the Weight of the object? If so, write the differential equation. If not, explain why
1c)Assume the population, P, of cats in a region is proportional to the area, A, of the region. Would it make sense to use differential equations to model the size of the population? If so, write the differential equation. If not, explain why.
1d) Assume the population, P, is changing at the rate proportional to (75-P). Does it make sense to use a differential equation to model the size of the population? If so, write the differential equation. If not, explain.
1e) If the rate of change, W, is inversely proportional to W and is always greater than 0. If W(0)=250 and W(2)=150, find the proportionality constant(k).

Q2- Fish Population In this question, we will use differential equations to study the fish population in a certain lake. An acceptable model for fish population change should take into account the birth rate, death rate, as well as harvesting rate Let P(t) denote the living fish population (measured in tonnes) at time t (measured in year) Then the net rate of change of the fish population in tonnes of fish per year is P'(t): P'(t) birth rate - death...

2. The growth rate of a population of bacteria is directly proportional to the population p() (measured in millions) at time t (measured in hours). (a) Model this situation using a differential equation. (b) Find the general solution to the differential equation (c) If the number of bacteria in the culture grew from p(0) = 200 to p(24) = 800 in 24 hours, what was the population after the first 12 hours?

3. A certain population of short lived insects is known to reproduce at a rate proportional to their current population. They are also known to reproduce at a rate proportional to the difference between the carrying capacity of their environment (the maximum population their envirnment can support) and their current population. The carrying capacity is proportional to their food supply, which changes with the season. The amount of food given in thousands of pounds is sin(t) + 2, where t...

Part B Please!!
Scenario The population of fish in a fishery has a growth rate that is proportional to its size when the population is small. However, the fishery has a fixed capacity and the growth rate will be negative if the population exceeds that capacity. A. Formulate a differential equation for the population of fish described in the scenario, defining all parameters and variables. 1. Explain why the differential equation models both condition in the scenario. t time a...
